PUMPING POWER.

SPECIFICATION forming part of Letters Patent No. 595,167, dated December 7, 1897.

Apulioation filed August 18,1897. Serial No. 648,640. No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE 1V. GRIMES, of Bluffton, in the county of ells and State of Indiana, have invented a new and Improved Pumping Power, of which the following is a full, clear, and exact description.

This invention relates to pumping powers for wells-such,for instance, as oil-wellsand by means of which the pumps of several surrounding wells are simultaneously operated.

The object of the invention is to provide a simple yet powerful machine having all its parts conveniently assembled an d with which a large frame is dispensed with, as well as supporting-rods.

I will describe apumping power embodying my invention, and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specificati on, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a vertical section of a pumping power embodying my invention. Fig. 2 is a top plan view thereof. Fig. 3 is a top plan View of an eccentric employed. Fig. 1 is a top plan view of another eccentric employed, showing a slight modification. Fig. 5 is a top plan view of a power-wheel employed. Fig. 6 is a plan View of a tie-plate and bearingplate employed. Fig. 7 shows a bearing-cup employed, and Fig. 8 is a plan view of the base.

The machine comprises a base 1, which may be bolted securely to any suitable foundation, as indicated at 2. The base 1 supports an upwardly-extended socket 3, and the socket is braced by means of wings 4., cast integral with the socket-wall and the base 1. Engaged in the socket 3 is a supporting-post 5, upon which the power-wheel and eccentrics are mounted, as will be hereinafter described. An adjustable wedge 6 extends through a transverse opening in the bottom of the socket 3 and also through a transverse opening in the post 5. The top of the opening through the post 5 will be inclined from end to end, and the upper edge of the wedge 6 will be correspondingly inclined. The object of this is to provide a simple means for adjusting the post 5 vertically, as may be required on account of wear.

Adjustably mounted on the socket 3 is a bearing-plate 7, through which the post 5 eX- tends. The plate 7 is provided in its upper surface with an annular raceway for hearingballs 8, and a plate 9 011 the post 5, above the plate 7, has a raceway formed in its under side and in which said balls 8 engage. The plates 7 and 9 will be of very hard metal and, as shown in Fig. 1, the plate 7 will have its edge extended upward in the form of a flange surrounding the plate 9. Thus a cup will be formed to hold oil for lubricating the ballbearings. The plate 7 has a central hub portion passing into an enlarged opening in the upper end of the socket 3, and the said plate 7 may be adjusted Vertically by means of screws 10, passing through lugs 11, extended outward from said plate, and the lower ends of these screws engage in the wings at.

Mounted to rotate on the post 5 is a powerwheel 12, having the inner ends of its spokes bolted in pockets formed in a hub 13. This hub 13 rests upon the plate 9, and in its upper portion it is provided with a depression to receive the hub 14: of an eccentric 15. The eccentric 15 is held from rotating relatively to the hub 13 by means of pins 16, engaging in holes formed in the hubs 13 and 14. The eccentric 15 has a depression formed in its top for receiving the hub 17 of an eccentric 18, and this eccentric 18 is provided with a depression in its top for receiving the lower end of a winding-drum 19, which is made hollow or cup-shaped, as shown, to receive lubricating-oil which may run down the post 5.

Pins 16 will be employed for securing the parts 15 and 17 together and the parts 18 and 19 together. The eccentric 15 has a peripheral groove formed with a substantially vertical wall and a substantially horizontal Wall, and in this groove an interior annular flange of the pump rod or line-plate 20 engages. The pump line-plate is held from Vertical movement by means of a ring 21, secured to the eccentric and extended slightly over the upper surface of the pump line-plate.

The eccentric 18 is similar to the eccentric 15, excepting that it has an annular raceway for ball-bearings 22, and the interior Wall of the pump line-plate 23 is transversely curved to engage with said balls. The pump lineplate 23 will be held from vertical movement by a ring 24:, similar to the ring 21. The eccentrics and the power-wheel are held together by means of long bolts 25, which pass through lugs 26, extended outward from the winding-drum 19, and the lower ends of these rods pass through openings in outwardly-extended lugs 27 of the plate 9. The heads of the bolts will engage the under sides of the lugs 27, and of course the nuts will engage with the bolts or rods above the lugs 26.

Preferably the inner portion of the hub, the

eccentrics,and the winding-drum will be filled with antifriction metal, as indicated in Fig. 1.

The post 5 is tapered at its part extended through the eccentric and drum, so that when any wear occurs the post may be made to fit tightly by raising it by means of the wedge 6. The power-wheel 12 I have shown as designed to be engaged by a band. lt is obvious, however, that a gear-Wheel may be employed in lieu thereof without departing from the the upper end of the socket, substantially as specified.

2. A Well-pumping power, comprising a post, eccentrics mounted to rotate on said post, a power-wheel mounted to rotate on said post with the eccentric, a base having a socket in which the lower end of the post engages, a bearing-plate adjustable on the upper end of said socket and having an annular channel in its upper surface, an upper bearingplate upon which the hub of the power-wheel rests, the said upper bearing-plate being provided with an annular channel or raceway, and bearing-balls in these channels or raceways, substantially as specified.

3. A well-pumping power, comprising a base provided with a socket, a bearing-plate adjustable vertically with relation to the socket, a post mounted in the socket and extended through the bearing-plate, a powerwheel mounted on the post, an upper bearingplate between the first-named bearing-plate and the bottom of the power-wheel hub, antifriction balls between these bearing-plates, eccentrics mounted to rotate on the post, a drum mounted to rotate on the upper end of said post, and tie-rods extended through the lugs on the drum and lugs on the top bearingplate, substantially as specified.
